6 Claims.

This invention relates to sill: thread oiling devices and has for an object to provide an improved ccnstruction adapted. to be used on silk winding machines, as, for instance, silk coning machines, the structure being such that a large number of threads may be oiled at the same time from the same oil supply.

Another object of the invention is to provide an improved silk thread oiler wherein oil is fed on to the thread by means which resiliently press the threads and thereby strain and rub down the loose strands.

A further object, more specifically, is the pro vision of a silk thread oiler wherein a comparatively long container is provided and supplied with a, plurality of slitted felt oil-feeding men1- bers positioned so that threads may be drawn through the slitted parts and supplied with oil from the felt.

In the accompanying drawing,-

Figure 1 is a perspective view of a silk oil threader disclosing an embodiment of the invention, the same being shown as connected with uprights forming part of a coning machine.

Figure 2 is an enlarged fragmentary sectional View through Figure l on line s-2.

Figure 3 is an enlarged top plan view of the outer end of an oil supplying felt shown in ure 2.

Referring to the accompanying drawing by numerals, 1 and 2 indicate uprights forming part of a coning machine, though they could form parts of other devices. Brackets 3 are bolted, or otherwise secured, to the uprights 1 and 2, brackets each having a slot 4, through which part of the clamping bolt 5 extends. On the bra-cipets 3 is mounted an oil container 6 formed from any desired material, as, for instance, sheet metal, and made rectangular in cross section and of the desired length. Bolt 5 extends through the bottom of this container, as shown in Figure 2, and by reason of the tension nut firmly clamps the container in a set position. The container 6 is provided with a number of notches 8, each notch accommodating a horizontal section 9 of the respective felts 10. A lid or cover 11 is provided for the container 6, said lid or cover having depending flanges telescoping over the ends and sides of the upper part of the container, as illustrated in Figures 1 and 2. At one end there is provided an aperture 12 through which oil may be deposited in the container 6, aperture being adapted to be closed by a swingably mounted cover plate 13. At the end opposite the opening 12, container 6 is provided with through the cover 11.

Figure 1,

As shown particularly in one of the downwardly extending flanges of the cover 11 is provided with a notch 18 for each felt so that the lid may be fully closed and yet the felt may extend in a horizontal direction as indicated. The felt 10 is provided with a horizontal section 9 extending outwardly and formed at its outer end with curved surfaces 19 merging into a slit 26, which in turn merges into an aperture 21.

The side walls are formed with the slit 2O usually in contact, but when a thread 22 is drawn through the slit, there may be a slight separation before the thread is resiliently pressed because of the resiliency of the parts 23 and 24.

The inner end of the felt 10 is formed with a depending section 25 which is continually in the oil 26, and, consequently, by capillary attraction the entire felt v16, including the section 9, are continually saturated with oil.

As the thread 22 is pulled through the felt and wound, it will naturally take with it a certain quantity of oil, but this is continually replenished by capillary attraction, drawingthe oil from the container 6. In case one of the said threads should break and be left unattended to, there will be no drippage of oil as the felt 10 will merely become saturated and remain so, but will not permit the oil to drop therefrom.

As shown in the drawing a number of felts are accommodated by the con tainer 6,

and, consequently, an independent thread may be treated by each felt. It is evident, however, that one or a large number of felts may be associated with the container 6 and associated parts without departing from the spirit of the invention. For commercial reasons, it is desirable to have a number operating at the same time, as, for instance, six or eight. order that the threads may move directly through the slit 26 there are provided guiding eyes 2'7 and 28, eyes 27 being supported by any desired means, not shown, while eyes 28 are connected to a bar 29 which bar is secured to substantially U-shaped straps 30 and 31, said straps fitting over the lid 11, as shown particularly in Figure 2.

The bar 29 may be moved longitudi- Ill nally in respect to the container 6 so that the various eyes 28 may be directly below the slit 20. However, after long usage the felt may become worn and there may not be sufiicient pressure against the felt to produce the desired rubbing and supplying of oil at the same time. When this is the case a new felt may besubstituted or the bar 29 may be moved longitudinally a short distance, as, for instance, a half inch, and this will cause the thread to rub against one of .the parts 23 or 24, thus providing a desired pressure. Also, by reason of the slot 4 in thebrackets 3, and the arrangement of the bolts 5, the container fi may be adjusted toward or from the supporting members 1 and 2. This adjustment is .desirable in order that when the devicezis first set in operation, the various threads 22 may be located sub stantially midway of the length of the slit 20. By reason of the curved surfaces 19 inergingzinto the slit 20, the thread may be threaded into the felt quickly and easily when the deviceiistjoriginally set up, or in case the thread rshould 'breakzat any time. As the device is used itJscrapes off :small particles fromthe thread and :in the course of time, some silk waste is:accumulated one'achifelt. This may be readily removed through aperture 21. If any of this waste is in theslita very fine wire or thread may be forced into .the slit and thereby force the waste intotheaperture2l from which it may be readily forced by a small pinor other implement.

I claim:

1. In a silk thr ad oiler including a container adapted to receive a quantity of oil, said container having a plurality of notches in the upperedge, a substantially L-shaped felt for each of said notches, each of said felts having onesectionextending horizontally through the respective notches and a second section extending downwardly into the oil of the container whereby the felt may be saturated with oil through capillary attraction, the horizontal :sections extending through said notches being slitted-and means associated with each felt for guiding a silk ithread through each slit.

2. A silk thread oiler including a container 'appreciably longer than it is wide, 'a plurality of felt members extending into the said container at spaced points, said container being adapted to receive a quantity-of oil, said felts being arranged so that one end 'Will be in contact with the oil and the other extending horizontally to a point exteriorly of the container, each of said felts be- -.container, said cover having notches in registry with the notches of the container, said cover having-a filling opening at one end and an oil gauge connected to said container at the opposite end,

aplurality of felt members having one end slitted .andextending horizontally through said notches, and theotherend projecting into the container to a point in contact with the oil therein, and means for guiding threads to the slitted parts of each ofsaid felts.

4. In a silk oiler, a felt member for supplying oil to threads and at the same time resiliently pressing the threads, said felt member comprising a body formed substantially L-shaped with one leg of the 1. extending horizontally and the other vertically, the horizontal leg being slitted from one end inwardly, said slitted part merging into a clean-out aperture.

5. A silk thread oiler including a container, means for supporting the container, said means including a plurality of slitted brackets and clamping bolts extending through the slits in the brackets, said bolts being rigidly connected with said container for clamping the container at different points on the brackets, a plurality of felt members extending from one vertical face of the container formed with openings through which threads to be oiled are adapted to pass, and means for guiding threads in vertical paths to said openings, the slits in said brackets being positioned to permit the adjustment of the container toward and from said threads.

6. A silk thread oiler including a container adapted to receive oil, a plurality of spaced L-shaped felt members positioned so that one leg of the felt member will be in said oil, and the other projecting horizontally from the container, the projecting part of each felt being slitted, a guiding eyelet adjacent the felts for guiding threads through said slits, and supporting means for supporting said eyelets, said guiding means being adjusted longitudinally of said container.
